FENCEWPOSTJEXTRACTOR.

SPECIFICATION forming part of Letters Patent N 0. 656,747, dated August 28, 1 900. Application filed April 27,1900. Serial No. 14,601. (No model.)

To all whom it may concern:

Be it known that I, FRANK MORGENTHALER,

a citizen of the United States, residing at Riesel, in the county of McLellan and State of Texas, have invented a new and useful Fence-Post Extractor, of which the following is a specification.

My invention relates to a novel fence-post extractor; and one object in view is to provide an apparatus of this character so constructed and arranged that it may be located alongside of a fence-post and operated to ex ert great leverage to pull the post in a direct vertical line.

A further object of the inven tion is to constitute the operative parts of the apparatus as guides which serve to retain the post in an upright position while being extracted.

Ordinarily in-devices of this general character the frame of the extractor is so constructed as to necessitate the location of the extracting mechanism directly over the post. By the employment of my extractor there is no necessity for any of the operative parts being extended over the post, inasmuch as the drums are located in vertical alinement and are presented directly against the side of the post, the frame being stayed by supports or braces which extend only from that side of the drum-supporting uprights opposite the post.

To the accomplishment of the objects stated my invention consists in the novel construction and arrangement of the parts of the extractor, all as will be hereinafter fully described, illustrated in the accompanying drawings, and succinctly defined in the appended claims.

In said drawings, Figure 1 is a perspective View of my extractor, illustrating this application. Fig. 2 is a side elevation thereof; and Fig. 3 is a central longitudinal section, the elevated or extracted position of the post hein g shown in dotted lines.

Referring to the numerals of reference used to indicate like and corresponding parts in the several views, 1 and 2 designate parallel uprights braced by suitable cross-bars 3 and 4:, located approximately adjacent to their upper and lower ends and preferably at their front and rear edges, respectively, and 5 and 6 indicate a pair of supports or braces connected at their upper ends to the standards 1 and 2 and downwardly divergently related thereto in order to constitute a brace to prevent rearward inclination of the standardsthat is 'to say, in the direction of the postwhen the extractor is in use. The supports or braces 5 and 6 are preferably connected adjacent to their lower ends to the standards, as by side bars 7.

8 indicates an operating and guide drum having terminal trunnions 9, journaled in the standards and designed to be rotated by a crank 10, keyed or otherwise secured upon one of the trunnions beyond. the adjacent standard. Around this guide and operating drum, the periphery of which extends slightly beyond the edges of the standards, is wound an operating-cable 11, which passes upwardly from the rear side of the drum and is fastened to and designed to be wound. upon an enlarged sheave 12, provided with a peripheral groove 13 for the reception of the cable and keyed or otherwise secured upon the extracting-drum 14, journaled, like the drum 8, between the uprights, but preferably of somewhat less diametelgin order that when the extracting-cable 15 is wound thereon in the operation of the machine the extreme diameter of the drum and wound cable will approximate the diameter of the drum 8. extracting-cable 15 is terminally fixed, as indicated, to the drum 1 1 and depends from the rear side of said drum and may be attached in any suitable manner to a fence-post 16. If desired, a guideblock 17 may be mounted upon the upright 2 in proximity to the drum 8 to prevent the operating-cable from working between the bearing-faces.

The operation of my device is as follows: Supposing the extraction of the fence-post shown in Fig. lrto be desired, rny extractor is presented alongside of the post, so that its upper end will be in contact with the drum 8. The cable 15 is now attached to the post in any desired manner, and the crank 10 is turned in the direction indicated by the ar- The eifect of this will be to cause the drum 8 to be rotated in the direction of the arrow to wind the operating-cable thereon and to cause the unwinding of said cable from the sheave 12. This operation will obviously effect the rotation of the sheave and the extracting or cable drum 1.4. at a less rate of The guided by them.

vserved that my extractor is of such peculiar drawn upwardly by the operating-cable it is guided in its movement and is retained in its true vertical position by contact with the operating-drum 8, which guides the post in its upward movement. As the post is drawn still higher its upper end contacts with the cable 15, wound upon the drum 14, and is now held firmly against both drums and is It will therefore be obconstruction and arrangement that its front portion is straight or flat to facilitate the movements of the operator and that it is supported or braced only from the side opposed to the post, so that the latter as it is drawn up travels along the face of the frame and is guided by both of the drums. The braces serve to prevent sidewise tilting of the frame, as well as to prevent it from being tilted in the direction of the post.

While the present embodiment of my inveniion is believed at this time to be preferable, I do not desire to limit myself to the structural details defined; but, on the contrary, I reserve the right to eifect such changes, modifications, and variations as may come properly within the scope of my invention.

What I claim is-- 1. In a fence-post extractor, the combination with a frame comprising parallel uprights, and supports extending from one side only of said uprights, of a pair of horizontal drums carried by the uprights in vertical alinement, means for operating said drums,-

and a cable carried by one of said drums and designed to be attached to a fence-post.

2. In a fence-post extractor, the combination with a frame comprising a pair of parallel uprights, and supports extending from one side only of said uprights, of an operatingdrum and an extracting-drum journaled inthe uprights and located in vertical alinement, a sheave carried by the extractingdrum, an operating-cable passed around the operating-drum and extending from the periphery of said drum at the rear of said frame to the periphery of the sheave at the front of the frame, an extracting-cable passed around the extracting-drum and extending from the periphery thereof at the rear of the frame, and a crank operatively connected to the opcrating-drum, whereby the rotation of the latter effects the opposite rotation of the extracting-drum to pull the post in a direct vertical line and in contact with both drums which serve as guides for maintaining the vertical position of said post.

3. In a fence-post extractor, the combination with a frame comprising a pair of uprights supported from one side only, of a pair of horizontal drums journaled in the uprights and located in vertical alinement, means for operating said drums, gearing intermediate of said drums, and an extracting-cable wound upon the upper drum, said upper drum being of slightly-less diameter than the lower drum in order to make the combined diameter of the upper drum and the rope wound thereon substantially equal to the diameter of the lower drum.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

FRANK MORGENTHALER.
